Mew Lake Campground is located within Algonquin Provincial Park along the Highway 60 corridor in Ontario. With just over 130 campsites, it is the only campground in the park to operate year-round.

Many sites sit within a White Pine forest, while others occupy a more open, scattered-tree setting. Roughly half the sites offer electrical hook-ups, and a dedicated loop on the west side of the lake (sites 95–131) is designated both dog-free and radio-free.

The campground also offers roofed accommodation in the form of four rustic cabins and six yurts, all accessible by vehicle and available in winter.

During the colder months, roads adjacent to most sites are plowed, and a heated, winterized comfort station provides drinking water, flush toilets, showers, and laundry.

The campground serves as a good base for hiking and biking trails, and the lake and surrounding area are known for wildlife sightings including moose, deer, beaver, and wolf.
